Product Description

About Wild Hydrangea: Though most species of hydrangeas originally come from Asia, several, including this one, are native to North America; this hydrangea survives cold weather better than almost any other available species. This plant also has the common name “sevenbark” because of the distinctive peeling of the bark to reveal the layers beneath. The name “hydrangea” comes from a Greek phrase meaning “water vessel,” possibly because of the plant’s constant need for water.

Wild Hydrangea Germination: Direct sow in spring, pressing the seeds into the surface of the soil; these seeds need light to germinate. Keep the soil moist until germination, which usually occurs within 10-14 days. To start indoors, place several seeds together in individual peat pots; keep the soil moist and in a location in indirect sunlight. This plant adapts well to clay soil as well as shallow or rocky areas.

Growing Wild Hydrangea Seeds: This plant needs consistent moisture, especially when becoming established. It can tolerate very moist soil that drains well, but tends to drop its foliage in drought conditions. Deadhead the spent blossoms for prolonged blooming. In good conditions this plant will spread rapidly by suckers, becoming rather weedy if left to itself; remove the suckers to prevent this. Cut back the plant to 8-10” during the time of winter or early spring dormancy.

Harvesting Wild Hydrangea: For fresh flowers, cut long stems of flowers that have just opened and place them in water immediately; strip the leaves that will fall below the water. These also make excellent dried flowers; bundle the stems and hang them upside down in a warm, dark place with good ventilation until dry.

Saving Wild Hydrangea Seeds: At the end of the season, the flowers will become dry and papery; shake the clusters of open seed heads over a container to remove the tiny brown seeds. Store the cleaned seed in a cool, dry place.
